The yarn pieces to be joined are stretched between the two pairs of suction tubes (28, 29; 30, 31) and untwisted by being wound about spindles (20, 21). Hot compressed air fed along the surface of two blocks (32, 33) adjacent to the untwisted yarn portions remove free fibers and distribute the fiber tufts in the base of a channel formed in said blocks (32, 33). Said tufts are retained in the base ...

Parallelepipedic packing containers are made and filled in succession by passing a continuous web of packaging material over a forming device which converts the web into tubular form with an overlapped longitudinal seam. The tube is then filled with the intended contents, e.g., a liquid and is then divided off into individual packing containers by first pressing the tube transversely at longitudin...

A system for assembling, processing and transferring battery cell elements including a plurality of element assemblers and an exit conveyor having a plurality of element conveying lanes. Each element assembler includes element transfer and processing apparatus comprising an endless chain conveyor having a plurality of longitudinally spaced element carriers adapted to successively engage an element...

A transmission case of an automatic transmission is formed with a fluid passage fluidly connecting a fluid pressure pump to a hydraulic control valve body for controllably operating a planetary gear system disposed in the case. The fluid passage is located adjacent a closed end of the transmission case and connected to control valve body in order to reduce the overall length of the transmission ca...

The shredder handles all sorts of combustible refuse, e.g. wood, grass or paper. A feed hopper (3) on top of a housing (1) is enclosed at the bottom by a screen (14). Inside the housing two parallel shafts (4,5) are fitted at a distance from each other, rotating in opposite directions. The shafts carry sets of cutter discs (6,7) axially staggered so that adjacent discs on the two shafts mesh, w...

Steering control means for automatic steering correction in an agricultural machine, especially a harvester for maize or like crops, comprises a change-over switch (7) in an electrical circuit between a regulator (12) and a measurement value transmitter (4) or a feedback transmitter (15), the signal voltages of the two transmitters being summated in the regulator. The switch (7) includes at least ...

The device comprises in a preferred embodiment, on one hand, an orienting system comprising a compass provided with two reflecting faces angularly offset 180 DEG , an orientable optical system for detecting the angular deviation of the reflecting faces relative to a reference direction and means for displaying the detected deviation and, on the other hand, an automatic piloting system comprising a...

The herbicide phenmedipham is prepared from meta-aminophenol by reaction with phosgene in an alkyl alkanoate solvent to make meta-hydroxyphenylcarbamic acid chloride, followed by reaction of the chloride with methanol and then reaction of the obtained methyl meta-hydroxyphenylcarbamate with meta-tolyl isocyanate, to obtain the required methyl 3-m- toylcarbamoyloxyphenyl-carbonate.

Sterile solution delivery and venting devices for use with multi-dose sterile solution packages are disclosed. The devices include a positive acting, normally closed check valve which opens to express solution from the package when squeezing pressure is applied and which automatically closes when the pressure is released. A hydrophobic filter is included to sterilize the replacement air which ente...

An aqueous dispersion of a pigment for use in a polymerization process to form a pigmented polyamide by addition of the dispersion to the polymer-forming reactants prior to completion of the polymerization is prepared by attrition milling a slurry containing about 70 to 80% by weight of pigment in water in the presence of a dispersing agent to separate agglomerated pigment particles, then with add...
